The future of microprocessors: nanolasers

February 7, 2011 - 5:42am | News | Other themes

Researchers at the University of California, Berkley, have developed a way to "grow" nanolasers on a piece of silicon which is believes to pave the way for new generation of laser processors.

In fact the silicon is bad at generating light. Scientists had previously tried to develop chips made of silicon and so-called "III-V" (three-five) semiconductor materials, but this approach has problems of its own.

Scientists have developed a new computer out of ice

September 3, 2009 - 7:15am | News | Other themes

Scientists have created the first chemical computer that works on the basis of crystallization of sodium acetate. This produces the so called sodium acetate trihydrate CH3COONa3H2O, which is known as hot ice as well.

The working principle is described this way: “We prepare a supersaturated clear solution of sodium acetate trihydrate CH3COONa3H2O, pour the hot solution into Petri dishes and cool the solution down to -5oC.
